T 0 all whom it may concern Be it known that I, HENRY H, MORETON, a citizen of the United States, residing at Venice, ,in the county of Los. Angeles and State of California, have invented a new and useful Electrical Heater, of which the following is a specification.

This invention is a heater of the type in which a parabolic reflector is employed, to project heat rays into the space which is to be heated. I

One of the objects of the invention is to provide a heater of the character mentioned, having means for insuring a uniform distribution of the heat rays in all directions, into the surrounding space. A further object is to provide means for radiating as well as reflecting'the heat rays. A further object is to provide eflective means for supporting the heating unit in operative relation with the reflector unit. A further object is to provide means for eflecting relative adjustment between the heating unit and the reflecting unit, whereby they may be brought into focus.

The invention will be hereinafter fully set forth and particularly pointed out in the claims. 7

In the accompanying drawings Figure 1 is a side elevation, partly in section, illustrating a heater constructed in accordance with the invention. Figure 2 is a similar view illustrating a slight modification. Figure'3 is a similar view illustrating a second modification. Figure 4 'is a side elevation and Figure 5 is a cross section illustrating a third modification.- Figure 6 is a side view of a fourth modification.

Referring to Figure 1 of the drawings, 10 designates a parabolic reflector constructed of any desired material, preferably thin metal, and provided with a central opening 11. A sleeve 12 is provided, the same being in register'with said opening and having a flange 13, secured to the reflector 10 in any desired manner. Said sleeve is preferably constructed of insulating material. Secured to the flange 13 are bracket arms 15, pivotally connected with a base 16.

The edge of the reflector 10, is provided with a flange 17, to which are removably secured upright rods 18, any desired number of rods being employed. Said rods areprovided with threaded ends 19, which extend through openings in the flange 20, of a concavo-convex parabolic radiator member 21, the convex face of which is polished. Said radiator member 21 is supported in juxtaposition over the reflector 10, by means of nuts 22, working on the threaded ends of the rods 18, the construction being such that the distance between the two units may be varied, as conditions require. I

Secured in suitable manner in the sleeve 12, for instance by means of set screws 23, is a screw shell 24:, in which is removably mounted the plug end 25, of a heating unit 26.. Said unit is of well-known construction. consisting of an approximately cylindrical body of insulating material, provided with a winding of resistance material, and having central and shell contacts of a type similar to those of the well-known standard electric light plugs. Said heating unit may be connected with a source of electrical energy by means of a standard plug 27, which screws into the shell 24, and contacts with the central contact of the heating unit. By loosening the set screws 23, the shell 24 may be adjusted inwardly or outwardly, to bring the heating unit into focus. a

In practice, the radiator unit 21, is adjusted to the desired distance from the main reflector 10, after which the plug 27 is connected up with the shell 24, in a well-known manner. The heat rays emanating from the heating unit 26, upon striking the concave surface of the reflector 10, are directed upwardly in straight lines, and impinge against the polished convex surface of the radiator unit 21, from which they are reflected in approximately horizontal lines, into a zone surrounding the'heater. In the course of a very short time the radiator'unit 21, will become heated. and in addition to the functionrof reflecting heat rays laterally therefrom, it will also radiate heat both upwardly and laterally. By means of this construction. a very large space may be heated to a high temperature; in a very short time.

In the form illustrated in Figure 2, the radiator unit 21 is provided withperforations 30, which permit a certain amount of the heat from the reflector 10, to enter a closed heating chamben'formed by said radiator unit and a convexed cover 31, secured in place in any desired manner. Said chamber soon absorbs suflicient heat to produce substantial radiation, the convexed cover 31 serving to radiate heat into a substantially hemispherical zone.

In Figure 3 is illustrated a form of the in- -vention, in which a plurality of superposed units are employed. In this form, the main reflector 35 is supported in any desired manner upon a suitable base, conventionally illustrated at 36, and provided with a sleeve 37, having a screw shell 38. A supplemental reflector 39 is supported over the reflector 35, in the manner already described in connection with Figure 1, said reflector being provided with a central opening 40. Supported above the supplemental reflector 39, by means of rods 41, in a manner similar to that described in connection with Figure 1, is a radiator unit 42,an'd it will be obvious that any number of superposed reflector units may be built up in the same manner. The convex surfaces of the supplemental reflector 39 and of the radiator unit 42 are polished. The radiator unit 42 is closed by a removable cover 43, thereby providing a heating chamber. The heating unit 44 is provided at one end with a threaded plug 45, complemental to the shell 38, andnthe other end is provided with a support 46 which is riveted or otherwise secured to the radiator unit 42. The plug 45 is shaped to project beyond the shell 38, whereby it may be engaged with a wellknown type of ferrule socket.

It will be noted that the heating unit 44 extends through the opening 40, of reflector 39. Thus in operation, each of the reflectors 35 and 39 gathers heat rays from the heating unit, and directs them upwardly against the bottom of the next adjoining superposed unit, thereby providing a heater of great capacity. In addition to the lateral reflection thus obtained, the radiator unit 42 with the cover 43, co-operates to provide a heating chamber from which heat will radiate into the surrounding space.

v In lieu of employing parabolic reflectors of circular cross section, they may be of elongated form as illustrated in Figures 4 and 5. In this form the main reflector unit 45 and the radiating unit 46, are provided with flanges 47, by means of which they may be mounted upon lugs 48, carried by a supporting frame 49. Said units are of general U-shape form in cross section, the curvature being parabolic. Suitably supported within the main reflector 45, is a heating unit 50, provided with means whereby it may he engaged by a standard plug 51. The bottom face of the radiator .unit 46 is polished, and the operation is substantially shaped to reflect th heat rays in one direction through an opening 54. Thehood 52 is provided with flanges 55, which are suitably secured to a similar flange carried by the main parabolic reflector 56, which is supported upon astand. The reflector 56 and its heating unit may be of any type, but preferably conform to the disclosure illustrated in Figure 1.
